Thank you very much!But I want the VI to work like this:When I click the "save" button,it can open a menu to decide where  to save,when I click the "open"button, I will see a menu that I can choose a picture to open.Could  you do that?

thanks!

You can use an event structure to detect the "save button" press.

Then a file dialog to select the location to save the image.

Then just modify the code above to do what you want it to do.

Similar thing for the open button.

Which image do you want to save? Acquired from the camera? if so you can put the grab/acquire in a while loop and use the stop button  as the trigger to save the image. For a pop to open as hornless rhino as suggested there is a ready made file dialog that you can use instead of hard wiring the file path shown above..
